Hammond 18G3933 39 x 33 In Galvanized Steel Enclosure Inner Panel

The 18G3933 is a 39 x 33 in (991 x 838 mm) galvanized steel inner panel from Hammond's 18P Series, sized for a wallmount enclosure measuring 42 x 36 in (H x W). It gives panel builders, electricians and OEM engineers a flat sub-panel for mounting equipment inside the enclosure. The 18P Series covers inner panels for 1418, 1447, PJW and PHW wallmount enclosures.

The series specification describes the galvanized panels as 12 gauge unpainted galvanized steel. Hammond's short description for this part reads "GALV PANEL FOR WALLMT 42X36". The same specification notes that some larger panels in the series are 10 gauge. The part drawing shows a material thickness of 0.10 in. At 39 x 33 in this is one of the wider galvanized panels in the range, and its drawing calls for eight mounting holes rather than four, spread on 18.63 in pitches down the length and 15.63 in pitches across the width.

Per the series ordering table, the panel measures 39.00 in (991 mm) long by 33.00 in (838 mm) wide and is matched to an enclosure 42.00 in (1067 mm) high by 36.00 in (914 mm) wide. The drawing specifies eight 0.50 in diameter mounting holes, spaced 15.63 + 15.63 in across the width and 18.63 + 18.63 in along the length.

Panel mounting hardware is not included with the 18G3933; the series specification notes that it is provided with the enclosure. The part is listed as RoHS and REACH compliant, and ships in a box with a shipping weight of 43 lbs (19.50 kg). The same size is also listed in steel (18P3933) and stainless steel (18P3933S16).
